Coordinated Control of Flexible AC Transmission System Devices and Power System Stabilizer for improve the Power System Stability Using Fuzzy Adaptive Bacterial Foraging

Abstract

Due to the development of power networks and the ever increasing use of Flexible AC Transmission Systems (FACTS) instruments, the unpredicted interactions have been increased in the power system. Thus, the designing and setting of proper controllers is crucial for the improvement of the dynamic response of a power system along with the FACTS instruments. Because of that in this paper, a new optimization algorithm-based method of Fuzzy Adaptive Bacterial Foraging (FABF) has been used to design the Power System Stabilizer (PSS) and the Thyrist or Controlled Series Capacitor (TCSC) for damping the low frequency oscillations of the power system. The aim of this design is to minimize the deviation of speed and generators terminal voltage in a great range of loads with the use of FABF algorithm. Designing of TCSC and PSS has been both independently and simultaneously performed to confirm the discussed method. The comparison of this method with the Particle Swarm Optimization algorithm (PSO) in the4-machine Kundur system and the10-machine New England system, shows the superiority potential of this method.

Modified Particle Swarm Optimization Based on Lead-Lag Power System Stabilizer for Improve Stability in Multi-Machine Power System

“…The E. coli bacteria that are existing in our guts also undergo a foraging policy. The control system of these bacteria that dictates how foraging should proceed can be sectioned into four sections as follow [6]: The chemotaxis step: control system is attained by swimming and tumbling via flagella. Therefore, the E. coli bacterium moves in two different techniques; it can run or tumble, and alternate between these two modes of procedure in the whole epoch.…”

“…Therefore, the E. coli bacterium moves in two different techniques; it can run or tumble, and alternate between these two modes of procedure in the whole epoch. To represent a tumble, a unit length random direction, approximately, ∅_j is generated; this will be used to describe the course of crusade after a tumble [6,30]. In actual…”

“…Adding control devices in coordination with the optimized PSS on the system to develop the power system stability similar to using a new optimization algorithm-based method of Fuzzy Adaptive Bacterial Foraging (FABF) used to design PSS and the Controlled Series Capacitor (TCSC) for damping the LFOs [6], and apply coordination between proportional-integralderivative (PID-PSS) enhanced by Firefly (FF) with the static synchronous series compensator (SSSC) [7].…”

Application of TC SC in Enhancing Dynamic Performance of Interconnected Multimac hine Power System

“…The application of TCSC in power system stability improvement has been investigated by several researchers. Recent results can be found in [6][7][8][9][10]. In [6][7][8][9], TCSC was used to enhance the stability of small power systems.…”

“…Although, the TCSC has been successfully applied to enhance stability of small power systems, its performance, however, on larger interconnected multi-machine power systems is still unclear. In [10], an optimization algorithm-based fuzzy adaptive bacterial foraging (FAFB) has been used to design the PSS and TCSC for damping the low frequency oscillations of the power system. However, the investigation results reported in the paper were not very convincing since the eigenvalue analysis was not used to confirm the results.…”
